Answer:
- milk: 10 carbs
- snack bar: 14 carbs
Step-by-step explanation:
Let m and s represent the carbs in the milk and snack bar, respectively. The given relations are ...
4m +3s = 82
2m +4s = 76
Subtracting the first equation from twice the second gives ...
2(2m +4s) -(4m +3s) = 2(76) -(82)
5s = 70 . . . . . . . simplify
s = 14 . . . . . . . divide by 5
We substitute this into the second equation to find m.
2m +4(14) = 76
m +28 = 38 . . . . divide by 2
m = 10 . . . . . . subtract 28
There are 10 carbs in a glass of milk; 14 carbs in a snack bar.
Answer:
-13 + j*2
Step-by-step explanation:
The additive inverse of a complex number x = a +j*b
is a number y, such that
x + y = 0
This means that
y = -x = - a - j*b
Therefore
The additive inverse of 13 - j*2 is equal to
-(13 - j*2) = -13 +j*2
<u>Answer</u><u>:</u>
<u> </u><u>First</u><u> </u><u>option=$13950 is correct.</u>
<u>Why</u><u>?</u>
<u>Total</u><u> </u><u>other</u><u> </u><u>cost</u><u> </u><u>=</u><u>$</u><u>1</u><u>5</u><u>5</u><u>0</u><u>0</u>
<u>1</u><u>0</u><u>%</u><u> </u><u>saving</u><u> </u><u>on</u><u> </u><u>other</u><u> </u><u>cost</u>
=10% × $15500
=$1550
<u>So total cost target on other cost for next month</u>
=$15500-$1550
=$13950
